Who is the creator of Liu Ti calligraphy?

Liu Gongquan (778-865) was born in Jingzhao Garden (now Yaozhou District, Tongchuan City, Shaanxi Province), Han nationality. The younger brother of Liu Gongzhuo, the minister of war, was a calligrapher and poet in the Tang Dynasty. After the seven dynasties of Shixian, Mu, Jing, Wen, Wu, Xuan and Yi, the official reached the crown prince and served as the official of Hedong County, so the world was called "Liu". Xian Tong died in six years (865), aged 88, and was given to the Prince.

Liu Gongquan's calligraphy is famous for regular script, which is as famous as Yan Zhenqing, and is called "Yan Liu", and is also known as "four masters of regular script" with Ou Yangxun, Yan Zhenqing and Zhao Mengfu. Wang Xizhi, a beginner in calligraphy, later visited the famous calligraphers in the Tang Dynasty and thought that Yan Zhenqing He's calligraphy was the best, so he learned the skills of Yan Ou, and created his own "Liu Ti" between the charm of Jin people and Yan Ti calligraphy, which was famous for its strength and health, and later generations had the reputation of "Yan Gu". Liu Gongquan also writes poems. Complete Tang Poetry contains five poems, and Complete Tang Poetry contains one poem.
